UPDATE 4/7/17 8.50am: Sony has now removed the Anthem trailer uploaded to its PlayStation YouTube channel which featured Photoshopped Xbox One X buttons.

You can still see a screenshot of the slip-up below.

Fans noticed the footage was identical to the gameplay shown during Xbox's E3 conference, supposedly running on Xbox One X - and questioned whether this could also be representative of PlayStation 4 Pro.

Sony has not responded to our request for comment. EA directed us to Sony for more information.

ORIGINAL STORY 3/7/17 9.50am: PlayStation's YouTube channel has uploaded the in-engine Anthem footage shown at E3 running on Xbox One X - but with poorly-Photoshopped PS4 buttons.

Fans noticed the footage was identical but, given the benefit of the doubt, it could just be the same demo running on PlayStation 4 Pro, right?

Nope. Over the weekend, eagle-eyed viewers spotted someone had simply edited the footage to overlay PlayStation 4 controls. There are frames where the edit fades in where both the original Xbox control prompts and PS4 overlay can be seen.

Head to the 3:39 minute mark in the video below (and watch in slow-motion if you can) and you'll see this:

While this wouldn't be the first time gameplay footage has featured swapped out button prompts, Anthem in particular is an issue because the footage shows the Xbox One X version of the game - which may well not be representative of what PlayStation 4 Pro can achieve.
